Abstract

White and black dross are resulted from the recycling of aluminum. There are no established processes to recover valuable materials from black dross. Hydrometallurgical processes seem to be suitable for the treatment of aluminum dross. The salts in the black dross are recovered by dissolving with water. The residues are treated by either alkaline or acid leaching. Although the leaching rate of alumina by NaOH is lower than that by acid, its intermediates are more suitable to the production of alumina-based materials. The future direction for the treatment and recovery of valuable materials from aluminum dross is discussed.

알루미늄 재활용공정에서 화이트드로스와 블랙드로스가 발생한다. 블랙드로스에 함유된 유용 성분을 회수할 수 있는 공정은 아직까지 개발되지 않았다. 습식공정은 알루미늄 드로스의 처리에 적합하다. 블랙드로스에 함유된 염은 물로 용해시켜 회수할 수 있다. 염회수 후 잔사는 알칼리용액이나 산용액으로 침출한다. 알칼리용액에서 침출속도는 산성용액에서의 속도보다 낮지만, 중간생성물이 알루미나를 함유한 제품을 생산하기에 더욱 적합하다. 알루미늄 드로스의 처리 및 유용성분의 회수를 위한 방향에 대해 고찰했다.
